Compatibility
This module works with any 5V system, including Arduino Uno, Nano, ESP8266, and Raspberry Pi (with 5V pin). Simply connect VCC to 5V, GND to ground, and signal pin (if any) to a digital I/O. No additional components required for basic operation.
Wiring Notes
Connect red wire to 5V, black to GND. For modules with a third wire (enable/signal), connect to a digital pin and set HIGH to turn on the laser. Do not exceed 5V; a current-limiting resistor is built in. Avoid direct eye exposure.
Why Buy from Compoden
Every component is sourced from verified suppliers and tested for compatibility before listing. We've spent 10 years building projects for makers, schools, and institutions across India. Ships from Bengaluru in 3-5 days. If defective on arrival, replace within 7 days.
Is this compatible with Arduino?
Yes, it works directly with any Arduino board. Connect VCC to 5V, GND to GND, and the signal wire (if present) to any digital pin to control the laser.
Can I use this for a laser-based communication system?
Yes, by modulating the power pin rapidly, you can transmit data wirelessly over short distances, but ensure you use a proper driver circuit for high-speed modulation.
Does this module include a receiver?
No, this module is only a transmitter (laser diode). To detect the laser, you will need a separate light sensor like an LDR or photodiode.
